Method for producing balling resistant cashmere sweater

A cashmere sweater and anti-pilling technology, applied in textiles and papermaking, fiber treatment, weft knitting, etc., can solve problems such as fluffing and pilling, not effectively restricting fiber movement, and easy fluffing and pilling of finished cashmere sweaters , to achieve the effects of enhanced binding force, improved anti-pilling level, and less prone to pilling

Problems solved by technology

[0005] In this production process, in the twisting stage of the spinning process, the twist ratio of ply to single yarn is 0.4 to 0.55, so that the outer cashmere fibers in the yarn suffer from less tension and are less affected. When external forces such as friction act, it is easy to slip out of the yarn and fluff and pilling; in the milling process of finishing, traditional techniques and additives are used, which do not effectively restrict the movement of fibers, making the finished cashmere Shirts are prone to fluff and pilling

Abstract

The production process of no-pilling cashmere sweater includes the following steps: 1. selecting cashmere fiber material of fineness 14-16 micron and length 28-34 mm; 2. spinning, which has twisting step to form single yarn with twist of 450-500 / m and for common cashmere yarn of 35.7x2-41.7x2 tex fineness, doubling with twist of 248-340 / m and twist direction of s direction, and doubling / single yarn twist ratio of 0.55-0.68; 3. knitting cashmere sweater pieces in one flat knitting machine; 4. sewing the pieces in sewing machine into cashmere sweater in the required style; and 5. finishing. The present invention is superior to background technology, which has the technological problems of fuzzing and pilling.

Description

1. Technical field [0001] The invention relates to the field of textiles, in particular to a method for producing anti-pilling cashmere sweaters. 2. Background technology [0002] Existing ordinary cashmere sweaters, due to the characteristics of scales on the surface of cashmere fibers and short, thin, soft, smooth fibers, and poor cohesion between fibers, there are serious fluffing and pilling phenomena during wearing and washing, which affect the quality of cashmere sweaters. Appearance quality and service life. [0003] The current production process of ordinary cashmere sweaters is: [0004] Cashmere fiber raw material→spinning→knitting→garment→finishing→finished product inspection→packaging and storage. [0005] In this production process, in the twisting stage of the spinning process, the twist ratio of ply to single yarn is 0.4 to 0.55, so that the outer cashmere fibers in the yarn suffer from less tension and are less affected. When external forces such as fricti...
